What issue regarding Church structure was highlighted at the Council of Trent?

The Council of Trent, which convened in response to the Protestant Reformation, emphasized the need for a reorganization of the ecclesiastical hierarchy and the strengthening of bishops' authority within the Church. This council aimed to address the issues of corruption and abuses that were prevalent in the Church at the time. One of its significant outcomes was the reinforcement of the bishop's role not only as a spiritual leader but also as a key figure in the administration of the Church's governance.

By advocating for a more structured and authoritative hierarchy, the Council sought to ensure that bishops had the proper jurisdiction and responsibility to oversee the clergy, enforce Church teachings, and implement reforms. This was crucial in restoring the Church's credibility and reducing the influence of abuses that had contributed to the Protestant breakaway.

In contrast, the other options do not accurately reflect the objectives set forth by the Council of Trent. The council did not propose democratic elections for church leaders, nor did it endorse the concept of a hereditary priesthood or the establishment of lay advisory boards. These alternatives diverge from the historical context and aims of the council, which focused primarily on reinforcing theological and structural integrity within the Church itself.
